3. 505K for the rest of this manual to clearly delineate it from the other 505U products The 505K radio telemetry module is an economical solution for the remote monitoring of process signals The 505K can connect to digital pulse or analogue signals from process transducers and transmit these signal values by radio Although the 505K is intended to be simple in its application it also provides many sophisticated features This manual should be read carefully to ensure that the modules are configured and installed to give reliable performance The 505K has been designed to use a European licence free radio band at 869MHz The 505K uses the 869MHz 105U module as a receiver or repeater If you have not used 105U modules before please read the 105U User Manual prior to reading this manual The 505K module is a monitoring only unit that is it will only accept input signals and does not provide output signals The 505K has an internal radio transmitter it does not have a receiver to receive messages from another module The 505K transmits the value of an input signal whenever the signal changes and also after a pre configured time Each transmission message includes error checking to confirm the validity of the message At each transmission the 505K may be configured to repeat the transmission several times to ensure that the transmission is received correctly This is important if the radio path is marginal that is the radio signal is n
4. If the update time expires since the last transmission then the last measured value will be transmitted that is a new measurement will not be taken Normally the update time will be much longer than the sample time If the update time is less than the sample time then update messages may transmit the same value as the previous transmission as a new measurement has not yet been taken Overview e Measurements of the analogue signal are determined by the sample time and warm up time e Analogue value is transmitted if the measured value has increased by the configured sensitivity amount since the last transmission e Analogue value is transmitted if the input value has not been transmitted within the update time 10 seconds 7 days e There is no paralysis time for the analogue input 2 4 6 Setpoint Status The setpoint status is an internal status value calculated by comparing the analogue input to two configurable setpoint values The setpoint status turns ON when the analogue input moves below the low setpoint value and turns OFF when it moves above the high setpoint value The high setpoint percentage must always be greater than or equal to the low set point The internal setpoint status will be determined every time an analogue measurement is taken The setpoint status is treated as a digital signal and its value is transmitted according to the rules for a digital input 2 4 7 Supply Voltage The 505K measures the supp
5. A zero rate steady level will correspond to a 50 analogue signal The analogue signal will be more than 50 if the level is increasing and less than 50 if the level is decreasing If an incremental shaft encoder is used then the rate may be scaled by scaling PRATE1 Ifa quadrature encoder is used scale PRATE2 The scaling value will determine both the 100 analogue signal e g 20mA and 0 signal e g 4mA For example if a maximum pulse rate of 10Hz is configured then the analogue signal will be 100 if the encoder increases at 10Hz 50 if the encoder pulse rate is 0 0 if the encoder decreases at 10Hz 75 if the encoder increases at 5Hz 25 if the encoder decreases at 5Hz Note that this is only true if the pulse inputs are configured for a shaft encoder If standard pulse inputs are used then 0 analogue signal will correspond to zero pulse rate 0Hz The pulse rates are treated as analogue inputs and follow the rules for an analogue input as described below 2 4 5 Analogue Inputs The analogue input can measure from 0 24mA or 0 1OVDC Current or voltage input can be selected by an internal selector refer Installation section of this manual The mA input can be used for conventional 4 20mA signals or 0 10mA or 0 20mA The voltage input can be used for 0 5 or 0 10VDC signals The 505K unit is factory configured for a 4 20mA signal however the user can calibrate the unit for other ranges The measurement resoluti

22. d incremental shaft encoders A shaft encoder is a transducer that measures level or displacement and has two pulse signals to indicate change of level and direction of change Both pulse inputs are read at the same time The divider parameter on PI2 must be set to 1 for this application If an incremental encoder is used then the calculated count value is stored in PIl Ifa quadrature encoder is used then the calculated count value is stored in PI2 The counter value or level position can be manually set using the 905K diagnostics features refer section 5 of this manual Initially the counter will need to be zeroed when the shaft encoder is in the zero level position 2 4 4 Pulse Rates The rate of each pulse count is calculated and can be transmitted as internal analogue inputs The rate is calculated on the increase of the base counter not the rate of the input pulses The maximum count rate which can be calculated is 1000Hz For PII this is the maximum pulse rate that can be calculated For PD a divider can be used for pulse rates more than 1 KHz The pulse rate values can be scaled that is the user can configure what pulse rate 0 1 1000Hz corresponds to maximum analogue value 20mA Each pulse rate can be scaled individually Note that this is separate to the divider on PI2 count If the pulse inputs are configured for a shaft encoder a pulse rate is still calculated corresponding to rate change of level
23. e For PD there is a configurable scaling divider integer 1 255 This allows the pulse count to be scaled If a divider of X is configured then the pulse count will increase by 1 for each X input pulses There is a separate divider for each pulse input The divider parameter could be used for the following reasons gt If the pulse count is to be transmitted to a pulse output on a 105U then the maximum pulse rate is 100Hz If the input rate is more than 100Hz then it can be reduced with the divider For example if the maximum input rate is 300Hz then the use of a 10 divider will bring the effective rate down to 30Hz each output pulse will then represent 10 input pulses gt The divider can be used to scale the pulse count to engineering units For example if the input pulse rate is 7 pulses per m of gas then a divider of 7 will result in a pulse count corresponding to the number of m Note that the divider must be an integer gt The divider could be used to slow down the pulse rate If the input pulse rate is 5KHz then the base 16 bit counter will overflow in approx 13 seconds If the overflow counter is not used then this may be too fast to be processed by HMI software If a divider of 100 is used then the counter will take over 20 minutes to overflow There is no divider for PIL If the pulse count is transmitted to a pulse output on a 105U module the 105U will compare the input count to its own output count the cou
